[frontier] How to handle dynamic tool updates without redeploying the agent

Implement runtime MCP server discovery with capability filtering: query /tools/list endpoints at initialization and periodically refresh, filtering by capability metadata rather than hardcoding tool schemas in config files.

Journey Context:
Teams currently static-configure MCP tools in YAML/JSON, requiring full redeploy when backends change. The alternative is hot-reloading, but naive implementation risks schema mismatch errors. Runtime discovery with Pydantic schema validation on the client side provides flexibility while maintaining type safety. This pattern is emerging in production MCP clients where tool registries are treated as dynamic DNS for capabilities.
